Why Are Electrodes Placed in Ecg

By placing electrodes on the skin it is possible to detect these electrical currents. The electrocardiograph (ECG machine) compares, amplifies and filters the electrical potential differences recorded by the electrodes and presents the results as ECG leads.

What is the purpose of the electrode ECG?

Electrode leads on the chest wall are able to detect electrical impulses that are generated by the heart. Multiple leads provide many electrical views of the heart. By interpreting the tracing, the physician can learn about the heart rate and rhythm as well as blood flow to the ventricles (indirectly).

Where are the electrodes placed for an ECG?

Electrode placement for a 12-lead ECG is standard, with leads placed on the left and right arm and left and right leg. Another pair of electrodes is placed between the fourth and fifth ribs on the left and right side of the sternum.
